Is your AC acting strange? If so, it's good to pay attention because it’s trying to tell you something.

The signs of an air conditioner’s problem can tell a lot about the type of issue the system is experiencing. Whether it’s peculiar noises, leaks, freezing up or another problem—it all points to a particular culprit and requires a specific repair. By identifying the specific symptoms, you can narrow down the potential causes of the problem and determine the best course of action for repairing the unit.

While the symptoms are often unique, many cooling system issues stem from problems that can be avoided by scheduling regular air conditioning maintenance. That’s because a routine Air conditioner maintenance call includes an inspection and cleaning of your system, as well as finding any parts that may be wearing out and need replacement or to be fixed. This helps find potential problems before they cause malfunctions or other issues.

Here are a few of the typical AC problems and the indications you may see:

Why Is My Air Conditioner Leaking?

An air conditioner leaking water can be a frequent issue. One of the most common causes of an AC leak is a plugged condensate drain line. The condensate drain line is designed to remove excess moisture from the air conditioning system. When this line becomes plugged with dirt, dust or mold, water can back up and start to leak.

Another potential cause of water leaking from an air conditioner is a broken or rusted drip pan, which can allow water to overflow and leak out of the unit. Also, a refrigerant leak or a malfunctioning pump can also cause water to leak from an AC unit.

It's crucial to address a leaking air conditioner quickly to avoid damage to your home and make sure that your air conditioning system is running efficiently. Routine air conditioner maintenance, including exchanging the air filter, checking the condensate drain line and inspecting the unit for damage can help prevent leaks from happening.

What's the Reason My Air Conditioner Freezes Up?

If your air conditioning is freezing up, it might stem from a variety of reasons. One frequent cause of a frozen air conditioner is reduced airflow, which can be caused by a plugged air filter, obstructed ductwork or closed vents. This leads to a buildup of cold air in the evaporator coil, causing it to freeze.

One more reason your air conditioner is frozen might be reduced refrigerant levels, which can cause the evaporator coil to become too cold and freeze. Leaking ducts or compromised insulation can also result in the buildup of cold air and cause the evaporator coil to freeze.

To fix a frozen air conditioner, it's important to turn off the system and allow it to thaw completely. Once the system has thawed, check the air filter, ductwork and refrigerant levels to see if something is broken. Regular maintenance, including exchanging the air filter and having the system inspected annually by a professional.

Why Does My Air Conditioner Make So Much Noise?

If your air conditioner is making loud noises, it could be a signal that the unit needs service. One common cause of a noisy air conditioner is a broken fan motor or a damaged fan belt. The loudness might also be a sign the equipment has loose parts such as screws, bolts or bearings, which can cause vibrations and rattling sounds.

A noisy air conditioner also may have a dirty condenser coil, which can prevent airflow and cause the system to work harder, resulting in increased noise. Additionally, a broken or old compressor can also produce loud noises from the air conditioner.

Why Is My Air Conditioner Not Blowing Cold Air?

One common cause of an air conditioning system not blowing cold air is a blocked air filter. A dirty air filter can significantly slow airflow, causing the evaporator coil to become extremely cold and freeze, resulting in a lack of cool air. Another plausible cause is a refrigerant leak.

Low refrigerant levels can also cause the evaporator coil to become too cold and freeze, leading to a lack of cool air coming from your air conditioning. Also, a faulty compressor or motor can also cause an air conditioner to not produce cool air. To address the issue, it's important to inspect the air filter and change it if necessary.

Why Won't My Air Conditioner Run or Start?

Your air conditioning system might not start up because of a tripped circuit breaker or blown fuse. To correct this, check the electrical panel and reset any tripped breakers or change any blown fuses.

Another possible cause is a malfunctioning thermostat, which can stop the air conditioner from starting. In this case, check the thermostat and replace it, if necessary. Also, a problematic compressor, motor or capacitor can stop the air conditioner from turning on. To address this issue, it's best to get a hold of a professional to inspect and repair the unit.

Why Is My Air Conditioner Making a Weird Noise?

In addition to the problem of air conditioners working louder than they should, sometimes they also make weird noises.

One typical cause of weird noises is a malfunctioning fan motor or a worn-out fan belt. These two dilemmas can produce scraping, squealing or grinding noises. Another possible cause is loose parts such as screws, bolts or bearings.

Furthermore, a dirty air filter can cause an AC to make whistling or wheezing noises, while a refrigerant leak can make hissing or bubbling noises.

As with many air conditioner woes, the root cause of strange noises is often something that can be reduced by regular air conditioning maintenance.
